Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
To Make Sugar Icing for Bride Cake
Ingredients
Directions
Make the icing
Beat the egg whites on a large plate until frothy.
Gradually beat in the sugar, a little at a time, to prevent the egg from falling.
Once all the sugar is incorporated, add the lemon juice and beat for an additional 30 minutes.
Finish the cake
Spread the icing evenly over the almond icing using a broad knife.
Apply the icing as soon as the cake comes out of the oven for best results.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Double-refined sugar
- Sweetens the icing and, once beaten in, gives it body and a thick, stable texture.
- Egg whites
- Whipped into a foam that traps air and gives the icing its light structure.
- Lemon juice
- Adds acidity that helps keep the egg white foam stable and adds a bright flavour.
The step that matters
Adding the sugar gradually. Sugar must be beaten in a little at a time so the egg white foam can absorb it and stay stable. Adding it all at once deflates the foam, leaving the icing runny and without structure.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
